Description

Technical Field

[0001] This invention relates to the field of production and processing technology, specifically to an intelligent cutting path optimization method for reducing material waste. Background Technology

[0002] Production and processing is a broad concept in the manufacturing and industrial production fields. Its core lies in transforming raw materials or semi-finished products into finished products through a series of operations. This process covers multiple stages such as cutting, shaping, assembly, and packaging, aiming to meet market demand and create economic value. Production and processing is value-added, which changes the form, performance, or function of raw materials to give them higher use value and market value.

[0003] In current cutting operations, materials are highly susceptible to shifting and wrinkling. Once the material shifts, the cutting position deviates from the pre-set path, causing the cut material size to fail to meet design requirements. If the size deviation of the cut pieces exceeds a reasonable range, problems such as uneven splicing and distorted garment shape will occur in subsequent sewing stages, severely affecting the overall aesthetics and wearing comfort of the finished garment. Material shifting also causes irregular cutting edges, exhibiting jagged or wavy edges, thus damaging the original shape of the material. Furthermore, when the material shifts, the cutting tools may generate unnecessary friction or collision with the material surface, scratching the surface and reducing material quality. Wrinkles also bring many problems to the cutting process. Wrinkles can cause uneven thickness in materials during cutting. When the cutting tool passes through wrinkles, the uneven force can alter the cutting trajectory, leading to deviations in the cutting dimensions. Furthermore, wrinkles can cause irregular deformation of the material during cutting, resulting in shapes that do not match the design, significantly reducing the product's pass rate. At the same time, wrinkled materials are prone to excessive compression and stretching during cutting, causing wrinkles or damage to the surface, severely affecting the product's appearance quality. Due to cutting quality problems caused by misalignment and wrinkles, a large amount of cut material becomes defective, requiring recutting or direct scrapping. This not only wastes raw materials but also incurs additional production time and labor costs. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent cutting path optimization method to reduce material waste, which has the advantages of stable material clamping, flexible adjustment of clamping position, and precise and stable guidance, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent cutting path optimization method for reducing material waste, the method comprising the following steps:

[0006] S1: Path Truncation: Take each inflection point on the proposed baseline cutting path as a cutoff point to obtain multiple baseline cutting path segments; obtain the outline of the target piece through pre-cutting as the actual cutting path, and take each inflection point on the actual cutting path as a cutoff point to obtain multiple actual cutting path segments.

[0007] S2: Error rate calculation: Select multiple reference path points on each reference clipping path segment, determine multiple actual path points on the actual clipping path segment corresponding to these reference path points, and calculate the coordinate error rate of each actual path point relative to its corresponding reference path point according to the formula L=[(mi-ai) / ai+(ni-bi) / bi] / 2. Take the average of the coordinate error rates of each actual path point as the error rate of the actual clipping path segment.

[0008] S3: Mark the easily biased clipping path segment: Mark the reference clipping path segment corresponding to the actual clipping path segment with an error rate greater than the predetermined error rate threshold as the easily biased clipping path segment.

[0009] S4: Pruning Path Optimization Strategy: If the number of easily biased pruning path segments is one, use that easily biased pruning path segment as the first pruning segment; if the number of easily biased pruning path segments is greater than two, use the easily biased pruning path segment with the highest error rate as the first pruning segment, use the easily biased pruning path segment with the second highest error rate as the transition pruning segment, and use the direction with fewer easily biased pruning path segments from the first pruning segment to the transition pruning segment as the pruning direction.

[0010] Furthermore, as a preferred embodiment of the present invention, in step S4, the first direction and the second direction are respectively taken as cutting directions. The number of easily deviated cutting path segments traversed from the first cutting segment to the transition cutting segment is the same. Then, when the first direction is taken as the cutting direction, the standard deviation m1 of the error rate of each reference cutting path segment traversed from the first cutting segment to the transition cutting segment is determined, and the standard deviation m2 of the error rate of each reference cutting path segment traversed when the second direction is taken as the cutting direction is determined. If the standard deviation m1 is greater than the standard deviation m2, the second direction is taken as the cutting direction; otherwise, the first direction is taken as the cutting direction.

[0011] Furthermore, as a preferred embodiment of the present invention, in step S1, pre-cutting involves cutting multiple layers of stacked fabric and selecting the cut piece located on the bottom layer of fabric as the target cut piece.

[0012] An intelligent cutting path fixing component for reducing material waste includes a placement platform, clamping mechanisms on both sides of the top of the placement platform, a fixing block fixedly connected to the front side of the placement platform, a driving mechanism at the center of the inner cavity of the placement platform, movable blocks on both sides of the inner cavity of the placement platform, a connecting mechanism fixedly connected to one side of each movable block, square blocks fixedly connected to the front and rear sides of each movable block, one side of each square block extending to the outside of the placement platform and fixedly connected to a support block, the top of the support block being fixedly connected to the clamping mechanisms, and guide mechanisms on both sides of the inner cavity of the placement platform.

[0013] Furthermore, as a preferred embodiment of the present invention, the clamping mechanism includes square plates disposed on both sides of the top of the placement platform. The bottom of the square plates is fixedly connected to a support block, and a clamping plate is disposed on the top of the square plates. Clamping blocks are fixedly connected to both the top of the square plates and the bottom of the clamping plates. A plurality of short rods are fixedly connected to the top of the square plates. The top ends of the short rods extend through to the top of the clamping plates and are fixedly connected to a limit block. A tension spring is sleeved on the surface of the short rods, and the two ends of the tension spring are fixedly connected to the square plates and the clamping plates, respectively.

[0014] Furthermore, as a preferred embodiment of the present invention, the driving mechanism includes a motor fixedly connected to the top of the fixed block, the output shaft of the motor being fixedly connected to a dual-axis threaded rod, one end of the dual-axis threaded rod penetrating into the inner cavity of the placement platform and rotatably connected to the placement platform, and two threaded blocks being threadedly connected to the surface of the dual-axis threaded rod.

[0015] Furthermore, as a preferred embodiment of the present invention, the connecting mechanism includes two second connecting members fixedly connected to one side of the movable block, an adjusting block being rotatably connected to the inner cavity of the second connecting member, a first connecting member being rotatably connected to one end of the adjusting block, and one side of the first connecting member being fixedly connected to the threaded block.

[0016] Furthermore, as a preferred embodiment of the present invention, the guiding mechanism includes two guide rods fixedly connected to both sides of the inner cavity of the placement platform. One end of each guide rod extends through to one side of the movable block and is jointly fixedly connected to a limiting plate. A spring is sleeved on the surface of the guide rod, and the two ends of the spring are fixedly connected to the limiting plate and the movable block, respectively.

[0017] Furthermore, as a preferred embodiment of the present invention, a groove is provided at the bottom of the inner cavity of the placement platform, and two sliders are slidably connected to the inner cavity of the groove, with the top of the sliders being fixedly connected to a threaded block.

[0018] An intelligent cutting path optimization method to reduce material waste includes the following steps in the use of fixed components:

[0019] Step 1: By starting the motor, the motor's output shaft drives the dual-axis threaded rod to rotate. The dual-axis threaded rod drives two threaded blocks to move relative to each other. The threaded blocks drive the first connecting piece to move. The first connecting piece drives one side of the adjusting block to move. The other side of the adjusting block drives the second connecting piece to move towards one side of the dual-axis threaded rod. The second connecting piece drives the movable block to slide on the surface of the guide rod, so that the two movable blocks move relative to each other. When the movable block moves, it will drive the spring to compress. At the same time, the movable block will also drive the square block to move. The square block drives the support block to move. The support block drives the two clamping mechanisms to move relative to each other.

[0020] Step Two: The user moves the clamping plate upwards, causing it to slide on the surface of the short rod. The clamping plate moves the top clamping block, and simultaneously, the clamping plate stretches the tension spring. When the clamping plate reaches a certain height, one side of the material is placed on top of the bottom clamping block. Then, the user releases the clamping plate, and the spring's rebound force moves the clamping plate downwards, causing the top clamping block to move as well. This clamps and fixes one side of the material. Since there are two clamping mechanisms arranged opposite each other, both sides of the material can be fixed, preventing the material from shifting during cutting. After fixing, the motor is started in reverse, causing the two clamping mechanisms to move in opposite directions, stretching the material and preventing wrinkles during cutting.

[0021] Beneficial Effects: The technical solution of this application has the following advantages: This invention has the advantages of accurate positioning of errors and reasonable marking of easily deviated paths. In actual use, by truncating the reference cutting path and the actual cutting path into multiple path segments and calculating the coordinate error rate of each actual path point relative to the corresponding reference path point, it can accurately locate the possible deviation positions during the cutting process, providing an accurate basis for subsequent optimization. According to the predetermined error rate threshold, the easily deviated cutting path segments are marked, allowing operators to intuitively identify areas prone to problems during the cutting process, facilitating targeted optimization. When determining the cutting order, the easily deviated cutting path segments with higher error rates are processed first, and the optimal cutting direction is selected based on the number of easily deviated cutting path segments traversed and the standard deviation of the error rate. This helps to reduce the accumulation of errors during the cutting process, improve cutting accuracy, and thus reduce material waste caused by cutting deviations. Pre-cutting selects the cut pieces on the bottom layer of fabric as the target cut pieces, which is closer to the situation of multi-layer fabric cutting in actual production, making the optimization method more practical and reliable.

[0022] This invention also possesses the advantages of stable material clamping, flexible adjustment of clamping position, and precise and stable guidance. In actual use, the clamping mechanism uses the elastic force of the tension spring to cause the clamping plate to move the top clamping block downwards, which, together with the bottom clamping block, clamps the material securely, effectively preventing material deviation during cutting, ensuring cutting accuracy, and reducing material waste caused by material deviation. Through the setting of the drive mechanism, the clamping position can be flexibly adjusted to adapt to the clamping needs of materials of different sizes, while also making it less prone to wrinkles during the cutting process. The guide rod in the guiding mechanism provides precise guidance for the movement of the movable block, ensuring that the movable block maintains linear motion during movement, improving the accuracy and stability of the clamping mechanism's movement, and further ensuring cutting accuracy.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. To better understand the technical content of the present invention, specific embodiments are provided and described in conjunction with the accompanying drawings. Various aspects of the present invention are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] As attached Figure 1 To be continued Figure 4 As shown: This embodiment provides an intelligent cutting path optimization method to reduce material waste, the method including the following steps:

[0032] S1: Path Truncation: Take each inflection point on the proposed baseline cutting path as a cutoff point to obtain multiple baseline cutting path segments; obtain the outline of the target piece through pre-cutting as the actual cutting path, and take each inflection point on the actual cutting path as a cutoff point to obtain multiple actual cutting path segments.

[0033] S2: Error rate calculation: Select multiple reference path points on each reference clipping path segment, determine multiple actual path points on the actual clipping path segment corresponding to these reference path points, and calculate the coordinate error rate of each actual path point relative to its corresponding reference path point according to the formula L=[(mi-ai) / ai+(ni-bi) / bi] / 2. Take the average of the coordinate error rates of each actual path point as the error rate of the actual clipping path segment.

[0034] S3: Mark the easily biased clipping path segment: Mark the reference clipping path segment corresponding to the actual clipping path segment with an error rate greater than the predetermined error rate threshold as the easily biased clipping path segment.

[0035] S4: Pruning Path Optimization Strategy: If the number of easily biased pruning path segments is one, use that easily biased pruning path segment as the first pruning segment; if the number of easily biased pruning path segments is greater than two, use the easily biased pruning path segment with the highest error rate as the first pruning segment, use the easily biased pruning path segment with the second highest error rate as the transition pruning segment, and use the direction with fewer easily biased pruning path segments from the first pruning segment to the transition pruning segment as the pruning direction.

[0036] Specifically, in step S4, the first direction and the second direction are respectively taken as the cutting direction. The number of easily deviated cutting path segments traversed from the first cutting segment to the transition cutting segment is the same. Then, when the first direction is taken as the cutting direction, the standard deviation m1 of the error rate of each reference cutting path segment traversed from the first cutting segment to the transition cutting segment is determined, and the standard deviation m2 of the error rate of each reference cutting path segment traversed when the second direction is taken as the cutting direction is determined. If the standard deviation m1 is greater than the standard deviation m2, the second direction is taken as the cutting direction; otherwise, the first direction is taken as the cutting direction.

[0037] When the number of easily biased trimming path segments is greater than two, the first segment and the transition segment are determined by sorting them according to their error rates; the optimal path is selected by comparing the standard deviations of the directions; the remaining paths are inserted into the trimming sequence according to their error rates from high to low to ensure overall efficiency and accuracy. Specifically: Assuming there are 5 easily biased trimming path segments (A, B, C, D, E), and the error rates are sorted as A>B>C>D>E, if A is the first trimming segment, B is the transition trimming segment, and there are two directions from A to B:

[0038] Direction 1: The path is A→C→B (passing through C);

[0039] Direction 2: The path is A→D→E→B (passing through D and E);

[0040] Calculate the standard deviations of all easily deviated path segments on the two-direction paths: the standard deviation of direction 1 (A, C, B) and the standard deviation of direction 2 (A, D, E, B). If the standard deviation of direction 2 is smaller, select A→D→E→B, and then trim in the order of D, E, C.

[0041] Specifically, in step S1, pre-cutting involves cutting multiple layers of stacked fabric and selecting the piece from the bottom layer of fabric as the target piece.

[0042] An intelligent cutting path fixing component for reducing material waste includes a placement platform 1, clamping mechanisms 2 on both sides of the top of the placement platform 1, a fixing block 3 fixedly connected to the front side of the placement platform 1, a driving mechanism 4 at the center of the inner cavity of the placement platform 1, movable blocks 5 on both sides of the inner cavity of the placement platform 1, a connecting mechanism 6 fixedly connected to one side of the movable block 5, square blocks 7 fixedly connected to the front and rear sides of the movable block 5, one side of the square block 7 extending to the outside of the placement platform 1 and fixedly connected to a support block 8, the top of the support block 8 fixedly connected to the clamping mechanism 2, and a guide mechanism 9 on both sides of the inner cavity of the placement platform 1.

[0043] Specifically, the clamping mechanism 2 includes square plates 21 disposed on both sides of the top of the placement platform 1. The bottom of the square plates 21 is fixedly connected to the support block 8. A clamping plate 22 is disposed on the top of the square plates 21. A clamping block 23 is fixedly connected to both the top of the square plates 21 and the bottom of the clamping plate 22. Several short rods 24 are fixedly connected to the top of the square plates 21. The top of the short rods 24 extends through to the top of the clamping plate 22 and is fixedly connected to a limit block 25. A tension spring 26 is sleeved on the surface of the short rods 24. The two ends of the tension spring 26 are fixedly connected to the square plates 21 and the clamping plate 22 respectively.

[0044] In this embodiment: by setting up the clamping mechanism 2, the elastic force of the tension spring 26 is used to make the clamping plate 22 drive the top clamping block 23 to move downward, and cooperate with the bottom clamping block 23 to clamp the material, which can firmly fix the material and prevent the material from shifting during cutting.

[0045] Specifically, the drive mechanism 4 includes a motor 41 fixedly connected to the top of the fixed block 3. The output shaft of the motor 41 is fixedly connected to a double-axis threaded rod 42. One end of the double-axis threaded rod 42 passes through the inner cavity of the placement platform 1 and is rotatably connected to the placement platform 1. Two threaded blocks 43 are threadedly connected to the surface of the double-axis threaded rod 42.

[0046] In this embodiment: by setting the drive mechanism 4, the motor 41 drives the double-axis threaded rod 42 to rotate, which can accurately control the moving distance and position of the threaded block 43, ensure the accuracy of the movement of the clamping mechanism 2, and at the same time make it less likely for the surface of the material to wrinkle during the cutting process.

[0047] Specifically, the connecting mechanism 6 includes two second connecting members 63 fixedly connected to one side of the movable block 5. The inner cavity of the second connecting member 63 is rotatably connected to an adjusting block 62. One end of the adjusting block 62 is rotatably connected to a first connecting member 61. One side of the first connecting member 61 is fixedly connected to the threaded block 43.

[0048] Specifically, the guide mechanism 9 includes two guide rods 91 fixedly connected to both sides of the inner cavity of the placement platform 1. One end of each guide rod 91 extends through to one side of the movable block 5 and is fixedly connected to the limiting plate 92. A spring 93 is sleeved on the surface of the guide rod 91, and the two ends of the spring 93 are fixedly connected to the limiting plate 92 and the movable block 5, respectively.

[0049] In this embodiment: the guide mechanism 9 ensures that the movable block 5 maintains linear motion during movement, improving the accuracy of the clamping mechanism 2. When the movable block 5 moves, the spring 93 acts as a buffer, reducing the impact force when the movable block 5 moves, protecting the components from damage, and also helping the movable block 5 to reset after movement.

[0050] Specifically, a groove 10 is provided at the bottom of the inner cavity of the placement platform 1. Two sliders 11 are slidably connected to the inner cavity of the groove 10, and the top of the sliders 11 is fixedly connected to the threaded block 43.

[0051] In this embodiment, the combined use of the groove 10 and the slider 11 serves to limit the movement of the threaded block 43, thereby improving the stability of the threaded block 43 during movement.

[0052] An intelligent cutting path optimization method to reduce material waste includes the following steps in the use of fixed components:

[0053] Step 1: By starting the motor 41, the output shaft of the motor 41 drives the double-axis threaded rod 42 to rotate. The double-axis threaded rod 42 drives the two threaded blocks 43 to move relative to each other. The threaded blocks 43 drive the first connecting piece 61 to move. The first connecting piece 61 drives one side of the adjusting block 62 to move. The other side of the adjusting block 62 drives the second connecting piece 63 to move to one side of the double-axis threaded rod 42. The second connecting piece 63 drives the movable block 5 to slide on the surface of the guide rod 91, so that the two movable blocks 5 move relative to each other. When the movable block 5 moves, it will drive the spring 93 to compress. At the same time, the movable block 5 will also drive the square block 7 to move. The square block 7 drives the support block 8 to move. The support block 8 drives the two clamping mechanisms 2 to move relative to each other.

[0054] Step 2: The user moves the clamping plate 22 upwards, causing it to slide on the surface of the short rod 24. The clamping plate 22 moves the top clamping block 23, and simultaneously, the clamping plate 22 stretches the tension spring 26. When the clamping plate 22 moves to a certain height, one side of the material is placed on top of the bottom clamping block 23. Then, the user releases the clamping plate 22, and the spring force of the tension spring 26 causes the clamping plate 22 to move downwards. The clamping plate 22 moves the top clamping block 23, thus clamping and fixing one side of the material. Since there are two clamping mechanisms 2 arranged opposite to each other, the clamping mechanisms 2 can fix both sides of the material, preventing the material from shifting during cutting. After fixing, the motor 41 is started in reverse, so that the two clamping mechanisms 2 move in opposite directions, which can stretch the material and prevent wrinkles from forming during cutting.

[0055] It should be noted that in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0056] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention shall be determined by the claims.

When the movable block (5) moves, it will drive the spring (93) to compress. At the same time, the movable block (5) will also drive the square block (7) to move. The square block (7) drives the support block (8) to move. The support block (8) drives the two clamping mechanisms (2) to move relative to each other. Step 2: The user moves the clamp (22) upward, causing it to slide on the surface of the short rod (24). The clamp (22) moves the top clamp (23), and the clamp (22) stretches the tension spring (26). When the clamp (22) moves to a certain height, one side of the material is placed on the top of the bottom clamp (23). Then, the user releases the clamp (22), and the spring force of the tension spring (26) causes the clamp (22) to move downward. The clamp (22) moves the top clamp (23), thus clamping and fixing one side of the material. Since there are two clamping mechanisms (2) and they are arranged opposite each other, the clamping mechanisms (2) can fix both sides of the material, preventing the material from shifting during cutting. After fixing, the motor (41) is started in reverse, so that the two clamping mechanisms (2) can move in opposite directions, thus stretching the material and making it less prone to wrinkles during cutting.
